This is the stuff that keeps our little house under power. The solar panels are 2 150 watt 12V panels and 1 75 watt panel, charging the batteries with up to 25Ah. It depends if we have summer or winter, in the summer the output goes down, but we have up to 11h of sun, in the cooler winter month we get more amps but only about 7 hours of sun. The solar panels react quite sensitive with high temperatures, over 40 degrees celsius. Common temperatures here in the summer.

Solarpanels
The big solar panels are mounted on a scaffolding pole, concreted 1 meter into the ground. They are movable so they aways face the sun. The small panel will have to be fixed soon, at the moment I just move it around.
Total length of the cable run from the big solar panels to the controler is about 5 meters, the small one got a 8 meter lead.The cable is 2x2,5mm and I seem to have no loss for that amount of cable length.

This is my controller. It will accept up to 30 amps from the solar panels and charges the batteries. I can also connect a timed 12V load to it, but I do not use this feature at the moment.

The controller will show how much power is being produced and how much is going into the batteries at any moment,as well as the total output per day/month/ever. Here on the right it puts 6.5A into the batteries and they are at 13.4V at the moment, so basically they are charged.
